A radiation fluoroscopy apparatus detects a marker and includes a control element, an image generation elementthat generates an image including an embedded marker inside the body of the subject based on a transmitted X-ray. A device candidate detection elementdetects the candidate of the marker, the local structure detection elementdetects the local structure in the target region in a proximity of the candidate point of the marker, the device determination elementdetermines whether the local structure is the device such as the marker or not, the device location acquisition elementacquires the gravity center coordinate of the local structure, and the device tracking elementtracks the marker based on the location of the marker in each frame.

Radiation fluoroscopy apparatus

A radiation fluoroscopy apparatus provides radiation fluoroscopy from at least three positions without moving the radiation irradiation element and the radiation detector. A control element includes a detection rate calculation element that respectively calculates the detection rate of the position of the marker in a first imaging system having a first X-ray tube and a first flat panel detector, a second imaging system having a second X-ray tube and a second flat panel detector, and a third imaging system having a third X-ray tube and a third flat panel detector, and a fourth imaging system having a fourth X-ray tube and a fourth flat panel detector; and an imaging system selection element that selects the two imaging systems, used for X-ray fluoroscopy, out of one of the imaging systems based on a detection rate of a position of a marker calculated by a detection rate calculation element.
